ELEVATED-RAILWAY STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 431,126, dated July 1,1890.

Application filed April 11, 1890. Serial No. 34=7A46- (No model.)

.To all whom it may concern.-

Be it known that I, JOSEPH STONE, of Bos ton, county of Suifolk, Stateof Massachusetts, have invented an Improvement in Elevated- RailwayStructures, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention in elevated railways has for its chief object such aconstruction and arrangement of the tracks with relation to the stationsthat all the stations of a double-track road may be arranged at the sameside of the street. Elevated railways as now commonly constructed have aseparate track and stations to which it runs on each side of the street,thus entailing great expense, especially in the purchase of sites forstations.

One object of my invention is to dispense with the stations at one sideof the street, yet secure all the efficiency of stations at two sides ofthe street, and at the same time I have so arranged the tracks andstations that express and local trains may be run on separate tracks inthe same direction, the express trains making stops at some stations andthe local trains at other stations without interference each with'theother.

In accordance with my invention I have arranged one road-bed overanother, each road-bed having two tracks, all the trains moving in onedirection running on the two tracks on one road-bed and the trains inthe reverse direction on the two tracks of the other road-bed. The localtracks are shown as arranged to pass the local stations at one side andthe express stations at the other side, the express trains passing allthe stations at one side and stopping at the express stations behind orat the other side of which the local trains pass and stop. In this waythe express and local trains can run at any desired speed and timewithout any interference with each other or danger of collision.

Figure 1 in vertical section represents an elevatedrailway structureembodying my invention, and Fig. 2 a plan view of one of the road-bedsrunning past stations arranged between blocks along a street.

The frame A, supporting the two road-beds B C, may be of any usual orsuitable construction, the frame being located at one side of thestreet. The road-bed B contains two tracks I) b, and the road-bed 0 twotracks 0 c.

The railway will have a series of local stations L at suitable distancesapart at one side of the street, and at proper intervals at the sameside of the street there will be a number of express stations E. Thesestations may be made over the sidewalk or in a suitable building, andaccess may be had to the stations by usual stairs or by elevators. Allthe trains on the tracks 17 b will be run in one direction, and those ontracks 0 o in the opposite direction. The express trains will run on thetracks I) c and the local trains on the tracks I) 0. Viewing Fig. 1, itwill be seen that the local tracks I) and 0', just alike on eachroad-bed, run past all the local stations at one side, and as they comenear an express station they pass to other or rear sides thereof, asshown. The local train on the local track may be stopped at all thelocal stations and at the express stations, if desired. The expresstrains on the tracks I) 0 run past the local stations L at one side ofand parallel to the local tracks, but do not stop at the local stations;but at the express stations the express track comes up to the side ofthe station, for the local track at the express station passes behindthe said station. In this way patrons of the road at an express stationmay take a car for any express or local station; but at a local stationa patron cannot get upon an express train.

The trains do not in any way interfere one with the other, and byputting all the stations at one side the street great economy iseffected in real estate and stations.

The structure for supporting the tracks may be of any desired kind, asthat is not of this present invention.

The herein-described system of elevated railway, it comprehending tworoad-beds, one above the other, an express and a local track on eachroad-bed, on which the cars travel in the same direction, and local andexpress stations, the local tracks being arranged to In testimonywhereof I have signed my pass the local stations at one side, and thename to this specification in the presenceof' express stations at theother side, While the two subscribing Witnesses.
